FQOTLIFT TO RAISE THE ASSEMBLING ELEVATOR OF TYPE-CASTING MACHINES.

Application filed an; 11,

T0 aZZ whom it may concern:

Be it known that 1, JOHN G. CLARK, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in F ootlifts to Raise the Assembling Elevators of Type Casting Machines, of which the following is a specification.

This invention relates to foot lifts to raise the assembling elevator of type casting machines, and consists of the novel features herein shown, described and claimed.

The invention will be readily understood from the following description of the accompanying drawings, in which- Figure 1 is a perspective view of a type casting machine having the improved foot lift for the assembling elevator attached thereto.

Fig. 2 is a perspective View of the improved foot lift.

Fig. 3 is a fragmentary detail section taken in the plane of the line 33 of Fig. 2.

Fig. 4 is a transverse section on the line 4-4 of Fig. 2.

The improved foot lift is employed in connection with the usual assembling elevator of a type casting machine in place of the usual hand lever for actuating the assembling elevator. By the provision of a foot lift for the assembling elevator l dispense with the necessity of the operator removing one hand from the keyboard of the machine for actuating the assembling elevator, and by the improved construction I provide means whereby sufficient power for lifting the assembhng elevator is readily obtained, the assembling elevator being arranged to return by its own weight to its lowered position.

The type casting machine upon which the foot lift is employed includes a usual sup porting base 1, and a magazine 2 from which matrices are discharged through the chute to the channel 4 of a usual. assembling elevator 5 arranged to be elevated, at the completion of a line, from its lowered position shown in Fig. 1 to raised position in aline ment with the intermediate channel 6.

The improved foot lift replacing the usual handle for raising elevator 5 is shown as comprising a link 7 secured to the assembling elevator and extending downwardly in front of the machine to a point adjacent the floor upon which the machine rests. A supporting plate 8 for the foot lift is shown suitably 192d. Serial no. 388,177.

bolted to the floor in front of the type casting machine and a rock arm- 9 extends across the plate 8 and is suitably hinged thereto as by the strap hinges 10 so that said arm may be swung upwardly from normal position resting against plate 8.

One end of arm 9 is outwardly bent as shown at 11 and said end is provided with a plurality of openings 12 at any one of which the end of link '7 is pivotally connected as by a bolt 13 extending through said opening. The opposite end of arm 9 is upwardly bent as shown at 14 and a spring 15, preferably, connects the end 14 to the plate 8 so as to yieldably retain the rock arm 9 in position with the end 14 extending substantially perpendicular from the plate 8. With the parts arranged as thus described, the assembling elevator will be in its lowered position, and when the rock arm is swung upon pivot 10 by a foot lever secured to the end 14 of said arm the link 7 will be raised so as to raise the assembling elevator, the distance to which the assembling elevator will be raised being adjustable to meet the requirements of various machines by changing the pivotal connection between link 7 and the end 12 of the rock arm from one to another of the series of openings 12.

The foot lever connected to the end of the rock arm is shown as a bar 16 extending transversely of the pivotal axis of rock arm 9. The end of bar 16 is provided with an angularly disposed foot rest 17 the end of which terminates in a lug 18 adapted to prevent lateral displacement of the foot relative to the foot rest. The bar 16 is, preferably, adjustably connected to the end 14 of the rock arm by a bolt 19 extending from said arm end through any one of a series of openings 20 arranged along bar 16. By this arrangement the leverage formed by the foot rest may be readily adjusted, the parts being so arranged that when pressure is exerted against foot rest 17 the rock arm will be swung against the tension of spring 15 for actuating link 7 so as to raise the assembling elevator.

In practice the operator will rest the heel of the foot upon the floor with the ball of the foot engaging foot rest 17 so that movement of the foot will readily depress the foot rest and thereby actuate the rock arm. Means are, preferably, provided for adjusting the rod 16 so that the foot rest will accommodate either a large or a small foot, such means being shown as comprising a support 22 secured to the end 1 1 of the rock arm and abutting against the bar 16 for forming a support for the same. The support 22 is shown as adjustable along arm end 14 so as to support bar 16 in pivotally adjusted positions, the support 22 for this purpose beino provided with an elongated slot 23 through which is received pins 24 secured tothe arm end 14 so as to adjustably position support 22. By this arrangement the foot rest may be swung toward or away from the floor as desired to meet the requirements of different size feet.

Various changes may be made without departing from the spirit of the-invention as claimed.

What is claimed is:

1. The combination with an assembling elevator for type casting machines, of a link extending down from the elevator to adjacent to the floor, a rocker shaft mounted on a support on the floor, a lever arm on the rocker shaft, extending forward therefrom and attached t0 the lower end of the link, and an upstanding arm on the rocker shaft provided with atoe rest for the foot of the operator. I

with a toe rest for the foot of the operator,

and means for adjusting the position of the rest as to the arm. I

In testimony whereof I have signed name to this specification.

JOHN G. CLARK.
